Pan-tilt-zoom camera and unmanned aerial vehicle

1. A pan-tilt-zoom (PTZ) camera, characterized by comprising a pan-tilt unit and a camera unit, wherein the pan-tilt unit comprises a first vibration damper plate, a second vibration damper plate, and a shock absorber ball; the camera unit is fixedly disposed on the first vibration damper plate, the shock absorber ball is sandwiched between the first vibration damper plate and the second vibration damper plate, and the shock absorber ball is fixedly connected to the second vibration damper plate; the shock absorber ball is elastic, and when the camera unit is horizontally laid, the first vibration damper plate is out of touch with the shock absorber ball; when the camera unit is subjected to extra load other than gravity, the first vibration damper plate compresses the shock absorber ball.

2. The camera of claim 1 , wherein the shock absorber ball comprises a mounting part, a connection part, and an elastic component; both the connection part and the elastic component are elastic; the connection part and the mounting part are fixedly connected, and the elastic component and the connection part are fixedly connected.

3. The camera of claim 2 , wherein the second vibration damper plate comprises a mounting hole, and the mounting part is inserted into the mounting hole to fix the shock absorber ball on the second vibration damper plate.

4. The camera of claim 2 , wherein the connection part is multiple in number, one end of each connection part is fixedly connected to the mounting part, and other ends of multiple connection parts are mutually fixedly connected to form a plane.

5. The camera of claim 4 , wherein the elastic component is fixed on the plane, and a gap exists between the connection parts and the mounting part.

6. The camera of claim 4 , wherein the elastic component and the connection parts are silica gel or rubber.

7. The camera of claim 1 , wherein the pan-tilt unit further comprises a fixing part, when the camera unit is subjected to extra load other than gravity, one end of the fixing part is fixedly connected to the second vibration damper plate, and the other end of the fixing part butts against the first vibration damper plate; and the fixing part is configured to limit the first vibration damper plate.

8. The camera of claim 1 , wherein the camera unit comprises: a lens module; a roll axis control module, being configured to fix and install the lens module, so as to allow the lens module to change postures along the roll axis; a yaw axis control module, being configured to fix and install the roll axis control module, so as to allow the lens module and the roll axis control module to change postures along the yaw axis; and a pitch axis control module, one end of the pitch axis control module being fixedly installed on the first vibration damper plate, the other end thereof being configured to fix and install the yaw axis control module, so as to allow the lens module, the roll axis control module, and the yaw axis control module to change postures along the pitch axis.

9. The camera of claim 8 , wherein the roll axis control module, the yaw axis control module, and the pitch axis control module each comprise a drive motor and a support, the drive motor is used for posture changes, and the support is used for fixing and installation.

10. An unmanned aerial vehicle, comprising a support part and a pan-tilt-zoom camera of claims 1 , the pan-tilt-zoom camera being mounted on the support part.
